Saether, Auburn, ind,assiguor to Van Norman Industries, lino, Garrett, Ind, a corporation ofMassachusetts Filed June 23, 1961, Ser. No. 119,088 12 Claims. (Cl.242-77) This invention relates generally to reels for accommodatingelongated material, such as wire, cable, strip material, etc., and moreparticularly to a take-up reel of the type having a removable flange.

In the past wire and other elongated material has been initially woundand shipped on reels made of wood or metal. Such reels were expensivethus necessitating the return of the empty reels from the wire consumerto the wire manufacturer, and thus the round trip transportation costfor reels, i.e. full of wire to the consumer and empty back to themanufacturer, has added appreciably to the cost of the wire to theconsumer. Because of this reel transportation cost, it is now thepractice to remove the coil of wire from the reel upon which it isinitially wound and to ship the coil, suitably bound, to the consumerwho then places the coil upon a suitable pay-off reel for use. Inaccordance with the present practice, take-up reels have been providedhaving radial slots formed in their heads or flanges with cooperatingaxial slots formed in the barrel to permit binding the coil of wire withsuitable strapping while the coil is still on the take-up reel. Suchreels further have a removable flange which then permits removal of thebound coil of wire from the reel for shipment to the consumer. In suchprior take up reel constructions, the removable flange has been securedto the reel by means of a conventional nut which engages suit-ablethreads, generally on the arbor tube.

in the process of producing an annular coil of wire on a take-up reel,lateral forces are created during the winding operation which areproportional to the tension employed during winding and inverselyproportional to the cross-section of the wire, these forces beingexerted laterally upon the flanges of the reel. Other variables such asthe dilferential in temperature of the wire at the time of winding andat the time of the flange removal will effect the magnitude of theselateral forces. In removing the flange from the reel for removal of theresulting annular package of wire, the nut must be unthreaded from thecooperating threads on the arbor tube. In prior take-up reelconstructions known to the present applicant, removal of the nut hasfrequently been most difficult if not in fact impossible due to theabove described lateral forces exerted on the flanges during the windingoperation. This difliculty in removing the nut and in turn the removableflange has frequently resulted in excessive downtime and loss ofproduction. It is therefore desirable to provide a take-up reelconstruction having a removable flange and in which the lateral-forcesexerted on the flanges during the winding operation do not hinder theremoval of the flange.

It is accordingly an object of my invention to provide an improved reelhaving a removable flange.

Another object of my invention is to provide animproved take-up reel forelongated material and having a removable flange in which the lateralforces exerted on the flanges during the winding operation do not hinderremoval of the removable flange.

A further object of my invention is to provide an improved take-up reelhaving a removable flange and in which minimum effort is required toremove the flange rev gardless of the lateral thrust exerted thereon bythe material on the reel.

Further objects and advantages of my invention will become apparent byreference to the following description and the accompanying drawings,and the features of novelty which characterize my invention will bepointed out with particularity in the claims annexed hereto and forminga part of this specification.

My invention in its broader aspects provides a reel for elongatedmaterial having a first annular flange member and an axially extendingtubular member coaxial with the first flange member and having one endsecured thereto. A second annular flange member is provided axiallyspaced from the first flange member and coaxial therewith, the secondflange member being removably positioned on the tubular member adjacentthe other end thereof. An annular locking member is provided threadinglyengaging one of the tubular and second members for axial movement withrespect thereto, the locking member having an annular tapered surfacespaced radially from the tubular member. One of the tubular and secondmembers has an annular groove formed therein, the groove having taperedsurfaces defining generally a V. A plurality of locking segments areprovided normally positioned between the locking member tapered surfaceand the second groove and respectively having first surfaces normallyseated in the groove and engaging the surfaces thereof. The lockingsegments respectively have other surfaces normally engaging the lockingmember tapered surface so that the locking member exerts a force on thesegments having an axial component and a radial component therebynormally locking the second flange mem her on the tubular member. Thesecond flange member has a portion exerting an axial force on thesegments responsive to the material on the reel exerting lateral forceon the flange members, such axial force being in the direction oppositefrom the axial force component exerted by the locking member. The firstsurfaces of the locking segments cooperate with the groove surfaces totend to move the segments radially out of the groove responsive to theforce exerted thereon by the second flange member portion, the othersurfaces of the segments cooperating with the locking member taperedsurface.

to assist removal of the locking member responsive to the radialmovement of the locking segments. H In the preferred embodiment of myinvention, a reel is provided with a barrel coaxial with the tubularmember for winding the material thereon, the barrel being formed of aplurality of arcuate segments. The first and second flange members haveannular portions thereon respectively normally supporting the barrelsegments in a first radially outer position, and means are providedmovably attaching the barrel segments to the tubular member andpermitting movement of the barrel segments to a second radially innerposition when the second flange member is removed from the tubularmember.

Referring now to FIGS. 1 and 2, there is shown a take-up reel, generallyidentified at 10, having fixed head or flange 12, a removable head orflange 14 and a barrel 16 upon which a coil of wire 18 is wound betweenflanges 12 and 14. In order to provide for banding the coil of Wire 18while it is still on the spool 10 in order to permit its removaltherefrom, flanges 12 and 14 are provided with a plurality of radiallyextending elongated slots 20 and the barrel 16 is provided with acorresponding plurality of axially extending grooves 22 whichrespectively communicate with the radial slots 20 in the flanges 12 and14. Thus, when the coil of wire 18 has been wound on the barrel 16,banding straps 24 may be respectively passed through the grooves 22 inbarrel 16 under the bottom layer of turns of the coil 18 and thenbrought upwardly through grooves 22 and across the outer layer of turnsof the coil 18 to be suitably connected, as at 26. The removable flange14 is then removed from barrel 16 as will be hereinafter more fullydescribed, the barrel 16 preferably collapsed, and the thus bound coilof wire 18 removed from the spool 10 for shipment to the consumer.

Referring now to FIGS. 3, 4, and 6, an arbor tube 28 is providedcoaxially disposed within the barrel 16 and the removable flange 14 issecured thereto by means of locking assembly 30. Locking assembly 30includes a housing member 32 having an annular outer surface 34 and anannular flange 36 to which the flange 14 is secured by means of aplurality of suitable threaded fasteners 38.

Housing 32 has an annular recess 40 extending therein from its end 42,recess 40 being defined by outer wall 44 and end wall 46. It will beseen that the recess 40 in the housing 32 surrounds the end 48 of arbortube 28.

The outer wall 44 of recess 40 is internally threaded, as at 50, and anannular locking member 52 is provided disposed in the recess 40 andhaving an externally threaded portion 54 threadingly engaging theinternal threads 50 of recess 40. Looking member 52 has a plurality ofspaced apart openings 56 formed in its end 58 which are adapted to beengaged by a suitable spanning wrench for turning locking member 52thereby to thread the same axially inwardly or outwardly with respect toend 48 of arbor tube 28, as shown by the arrows 60. Locking member 52has a locking surface 62 which tapers outwardly from its inner surface64 toward its end 66, i.e. toward the end wall 46 of recess 40.

The outer peripheral surface 68 of end 48 of arbor tube 28 has anannular groove 70 formed therein defined by tapered surfaces 72 and 74mutually defining a generally V-shaped configuration, as shown. It willbe observed that in the position of the locking assembly shown in FIG.3, groove 70 is generally in radial alignment with the locking surface62 of locking member 52.

A plurality of locking segments 76 are provided disposed around end 48of arbor tube 28 between groove 70 and locking surface 62 of lockingmember 52. Locking segments 76 respectively have tapered surfaces 78 and80 which respectively slidingly engage the tapered surfaces 72 and 74 ofgroove 70 inthe position of the assembly shown in FIG. 3. Lockingsegments 76 further have tapered outer surafces 82 which respectivelyslidingly engage the tapered locking surface 62 of locking member 52.

Housing 32 to which flange 14 is secured is slidably assembled on arbortube 28 and is restrained against rotation with respect thereto by meansof a suitable key 4 84. An arcuate groove 86 is formed in the side 88 ofeach of the locking segments 76, the arcuate grooves 86 forming acontinuous annular groove in which a suitable spring 90 is seated, asshown. Spring 96 urges or biases the locking segments 76 radiallyoutwardly.

The threaded portion 54 of locking member 52 is axially shorter'thanthreaded portion 50 and is spaced from end 58 of locking member 52 by anouter wall 92 which defines an annular space 94 with the internalthreads 50 of the housing 32. An annular retainer ring 96 is seated in asuitable annular groove 98 in the end 42 of housing 32 and is securedthereto by a plurality of suitable threaded fasteners 100. Retainer ring96 extends into the annular space 94 and is adapted to engage the end orshoulder 102 of threaded portion 54 thereby to limit the axial movementof locking member 52 outwardly, i.e. away from the end wall 46. Thus, itwill be seen that the locking member 52 cannot be readily removed fromthe lockingassembly 30 without first removing the retaining ring 96.

Flanges 12 and 14 respectively have annular tapered surfaces 104 and 106formed on their adjacent sides or faces 108 and 110, surfaces 104 and106 being respectively coaxial with and radially outward from the arbortube 28. Barrel 16 is formed of three arcuate segments 112, 114 and 116(FIG. 7) respectively having their ends tapered to engage the taperedsurfaces 164 and 106 of flanges 12 and 14. It will thus be seen byadditional reference to FIG. 8 that when the reel is completelyassembled, segments 112, 114 and 116 which form barrel 16 are supportedby the tapered surfaces 104 and 106 of flanges 12 and 14.

It will be seen that the flange 14 is secured to arbor tube 28 byrotating locking member 52 so as to thread the same inwardly toward theend wall 46 of housing 32, the sliding engagement of the tapered surface62 of locking member 52 with the tapered outer surfaces 82 of lockingsegments 76 forcing the segments radially inwardly so that inner taperedsurfaces 78 and 88 respectively engage the tapered walls 72 and 74 ofthe groove 70.

It will now be seen that when the coil of wire 18 is wound on the barrel16, a lateral force, as shown by the arrow 118 is exerted on the flange14, this lateral force in turn being transmitted through the housing 32and the end wall 46 thereof to the faces 88 of the locking segments 76.It will be seen that the force exerted by the tapered locking surface 62of locking member 52 on the tapered outer surfaces 82 of the locking sements 76 may be resolved into two components, i.e. an axial component offorce in the direction shown by the arrow 120 and a radial component offorce as shown by the arrow 122. It will further be seen that the forceexerted by the end wall 46 of the sides 88 of the locking segments 76 asa result of the lateral forces 118 exerted by the coil of Wire 18 on theflanges 12 and 14, as shown by the arrow 124, is opposite from the axialcomponent of force 120. It will finally be seen that the provision ofthe tapered wall 74 of groove 70 resolves the axial force 124 exerted byend wall 46 on faces 88 of locking segments 76 into a radial componentas shown by the arrow 126. The angle of the tapered wall 74 of groove 70is such that the radial component of force 126 acting upon the segments76 combined with the radially outward force exerted by the spring 90 issufficiently large to tend to move the segments 76 radially outwardly asthe locking member 52 is threaded axially outwardly, i.e. away from endwall 46. In a specific embodiment of my invention, the angle betweensurfaces 74, and a line perpendicular to the center line of the arbortube 28 is 25 and the included angle between surfaces 74, 88 and 72, 78is Inner radius 81 of segments 76 is preferably the same as the radiusof the outside diameter of arbor tube 28 in order to prevent scoring ofthe arbor tube when the segments are released from groove 70.

It will now be seen that the lateral forces 118 exerted on flanges 12and 14 during the winding of coil 18 on barrel 16 are employed to assistremoval of the locking member 52 and in turn removal of the removableflange 14 from the arbor tube 25. The radially outward movement of thelocking segments 76 is controlled by the tapered surface 62 of thelocking member 52 and continued axially outward threading of the lockingmember 52 results in outward movement of locking segments 76 away fromthe arbor tube 28 until they finally completely clear the groove 70, asshown in FIG. 4. When the locking segments 76 have cleared the groove70, the locking assembly 30 with the flange 14 secured thereto may thenbe removed completely from the end 48 of the arbor tube 28.

In order to retain the locking segments 76 in the housing 32 when thesame is removed from the arbor tube 28, and further to guide theirradial movement, a plurality of elongated slots 128 are provided in endwall 46 of housing 32, slots 128 being parallel with the radial movementof the segments '76. Pins 131) respectively extend through the slots 128and into the sides 88 of the locking segments 76 thereby guiding theradial movement of the segments 76 and retaining the same in recess 40of housing 32 even though locking member 52 may be completely removedtherefrom. When the removable flange 14 is removed from the arbor tube28, all of the parts which comprise the locking assembly 30 remainattached thereto rather than being separated as in the case of priorconsrtuctions and thus subject to being lost or becoming dirty.

Referring now to FIGS. 7, 8 and 9, it will be comprehended that the coilof Wire 18 is tightly wound on the barrel 16 and that its removaltherefrom even with the flange 14 removed from the spool, would bedifficult unless the barrel were collapsed. Thus, barrel 16 is formed,as previously indicated, of three arcuate segments 112, 114 and 116.Each of the barrel segments 112, 114 and 116 has a pair of elongatedsupporting members 132 and 134 secured thereto, as by suitable threadedfasteners 136, and extending inwardly therefrom, supporting members 132,134 being respectively parallel with the arbor tube 28 as best seen inFIG. 7. A pair of guide members 138 and 149 are secured to the arbortube 28 in spaced apart relationship, as shown. Each of the elongatedarbor tube supporting members 132 and 134 has a pair of elongated slots142 and 144 formed therein, slots 142 and 144 having their bottom ends146 and 148 respectively adjacent their bottom edges and taperingupwardly toward flange 12. t

The guiding members 138 and 141 respectively have transversely extendingguide pins 152' secured thereto, the pins 152 extending through theelongated slots 142 and 144 in the support members 132, 134.

It will be seen that with the arbor tube segments 112, 114, 116 in theirouter positions, i.e. with flange 14 assembled on arbor tube 28, theguide pins 152 are respectively at the bottom ends 146 and 148 of theguide slots 142 and 144. Referring now to the FIG. 9, it will be seenthat when the flange 14 is removed from the arbor tube 28 andparticularly when an eflort is made to remove the coil of wire 18 fromthe barrel 16, the segments 112, 114 and 116 collapse axially as shownby the arrow 15d and radially inwardly as shown by the arrow 156, thismovement being guided by means of the guide pins 152 in the slots 142,144 until the barrel segments reach their inner positions with the guidepins 152 at the upper-ends of the slots 142, 144.

It will be seen that the fixed flanged 12 is permanently secured toarbor tube 28 by means of suitable threaded fasteners 1S5- engagingannular flange 156 formed on end 158 of the arbor tube 28. In assemblingthe reel, the flange 12 is preferably horizontally disposed upon a flatsurface such as the floor, with the arbor tube 28 and the barrelsegments 112, 114 and 116 thus extending vertically upwardly. The weightof the barrel segments will thus cause them to fall downwardly fromtheir collapsed position as shown in FIG. 9, this downward movementbeing guided by pins 152 in slots 142, 144 of the support members 132,134 so that the downward movement of the barrel segments is accompaniedby a radial outward movement until ends 161 of the barrel segmentsengage the tapered surface 104 of flange 12, as seen in FIG. 8. Flange14 is then assembled on the other end of the spool with its taperedsurface 166 engaging the other ends 162 of the barrel segment 112, 114,116. Locking member 52 is then threaded axially inwardly, i.e. toward.end wall 46 of housing 32 thus forcing locking segments 76 radiallyinwardly into engagement with the groove 70. The assembled spool maythen be uprighted and positioned on suitable winding apparatus forwinding the wire thereon to form the coil 18.

It will be seen that I have provided an improved takeup reelconstruction incorporatnig a removable flange and collapsible barrel inwhich the locking member may ,be turned with a minimum of effortregardless of the amount of thrust exerted on the flange thus to permitready removal of the removable flange.
